The radio broadcasts most people are familiar with today didn't begin until after World War I. Until then, besides being a reliable form of communication between ships, the radio was used during the war to communicate to the front lines and top military officials. Once the war was over, communications in the United States and Britain began.
Radio caught on faster in Britain than it did in the U.S. Due to the devastation brought on by the war, Britain needed a way for its citizens to take their minds off their problems and radio provided the perfect release. Radio was used to transmit news, plays, music and discussion to people all over the United Kingdom and when word of radio's popularity spread to the United States, the country followed a similar path of broadcasting.
